Abstract
An air conveyor is positioned on a tabbing machine and includes a housing having an air chamber and a web entry and web exit and air port communicating with the air chamber. An air nozzle assembly is positioned within the air chamber and includes upper and lower nozzle plates that extend across the air chamber and spaced from each other to form a web delivery channel that is aligned with the web entry and web exit. Each of the nozzle plates includes a plurality of air nozzles extending through the nozzle plate and configured to pass pressurized air from the air chamber into the web delivery channel such that a web of material entering the web entry is drawn, for example, by venturi pressure, from the web entry through the web delivery channel and out the web exit.
